OK, I am having problems with this. I have been to Rehan's site and bought the PIP Plus so there's no expiry problems. It has installed OK. I am using WMM version 2.1 with XP Pro with SP2.
In my ADDOnTFX folder I have the "rec.png" image and the "rec.xml" (third version from the above thread) files and when I go into WMM I can see the "PIP Plus: Rec Screen" effect in the Video Effects. All sounds good right?
Wrong - when I go to add it to a clip in my movie, nothing happens - at all. The clip ...

As a matter of fact I am - how did you know? I have two 19" monitors so I can have two programs on screen at the same time - are you saying that if I switched to single monitor then I would see the effect?
